help: inexpensive reciever for outsie speakers

I have downsized my entire entertainment center. Smaller area inside I run B&W CM9 S2's with a Krell S-300i and OPPO BDP-105. I have a set of PSB CS1000's for my exterior and looking for an inexpensive but quality output receiver. I do not want to drop a lot of dinero on a receiver for the outside. Looking for something 100-120 watt two channel. I'm looking for suggestions, the Krell gives the PSB clarity, is there a lower budget receiver I could use and get close to the same results? Thank you in advance.
